Robert Wilhelm Eberhard Bunsen (German: [ˈʁoːbɛʁt ˈbʊnzn̩]; 30 March 1811 [a] – 16 August 1899) was a German chemist. He investigated emission spectra of heated elements, and discovered caesium (in 1860) and rubidium (in 1861) with the physicist Gustav Kirchhoff. [11] The Bunsen–Kirchhoff Award for spectroscopy is named after Bunsen ...
Rubidium chloride (RbCl) is probably the most used rubidium compound: among several other chlorides, it is used to induce living cells to take up DNA; it is also used as a biomarker, because in nature, it is found only in small quantities in living organisms and when present, replaces potassium.
A prefix meaning "two", e.g. bisulcate, having two sulci or grooves. biennial A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid
Ocimum tenuiflorum, commonly known as holy basil, tulasi or tulsi (from Sanskrit), is an aromatic perennial plant in the family Lamiaceae. [ 2 ] [ 3 ] It is widely cultivated throughout the Southeast Asian tropics .
The first instrumental analysis was flame emissive spectrometry developed by Robert Bunsen and Gustav Kirchhoff who discovered rubidium (Rb) and caesium (Cs) in 1860. [4] Most of the major developments in analytical chemistry took place after 1900. During this period, instrumental analysis became progressively dominant in the field.
In Sanskrit, this plant is known by the name Manjishtha. It was used by hermits to dye their clothes saffron. It was used by hermits to dye their clothes saffron. Dioscorides and Pliny the Elder (De Re Natura) mention the plant (which the Romans called rubia passiva).
They consist of several to many flowers, found at both the ends of branches and in the leaf axils. The flowers appear from August to September, followed by small (4–6 mm diameter) red to black berries from October to November. [2] The roots can be over 1 m long, up to 12 mm thick. It prefers loamy soils with a constant level of moisture.
Cress (Lepidium sativum), sometimes referred to as garden cress (or curly cress) to distinguish it from similar plants also referred to as cress (from Old English cresse), is a rather fast-growing, edible herb. Garden cress is genetically related to watercress and mustard, sharing their peppery, tangy flavour and aroma.
